Apologies if this has already been asked but search wasn't working.
In regards to the track audio_summary result/fields (i.e. danceability, energy, loudness, speechiness, liveness, ...) - it is right to assume (and can someone confirm) that the majority have the ranges 0.0-1.0 with the exception of loudness (what is this a measurement of) and tempo.
If not then is it possible to have the range value for each?
Cheers, J
